The Griffin is a light tank prototype that General Dynamics would like to sell to the Army. But since it’s not real yet, the company is using virtual reality to show Army leaders what it can do.

To do that, they brought an Oculus Rift virtual reality system to the annual Association of the United States Army conference in Washington, D.C., where anyone can immerse themselves in simulated combat to see how the Griffin moves and shoots — and they can do the shooting.
